Real-time personal broadcasting and video social network services on which a user’s mobile device serves as the content provider have received a considerable amount of attention. This letter presents an up-streaming video service in which a mobile device records and encodes video streams on the spot and transmits them to a receiver through an uplink interface. Unlike existing streaming services, the...
Existing video streaming protocols get poor QoE (Quality of Experience) especially when network bandwidth is drastically fluctuated due to handoff events over heterogeneous networks where they provide different bandwidths and network conditions. This paper proposes a novel QoE guaranteed mobile video streaming scheme over heterogeneous wireless networks: MOSQUITO. MOSQUITO can dynamically adjust streaming...
This paper proposes an adaptive edge-preserving smoothing and detail enhancement for video preprocessing of H.263. The proposed method consists of two steps: edge preserving smoothing using a motion-adaptive bilateral filter and detail enhancement using an adaptive high-boost filter. In the first step, the motion-adaptive bilateral filter preserves edges in region of interest (ROI) and smoothes noise...
